Illumination impact on image
BGA solder ball illuminated by front incident light only. Surface structure and shape are visible.
Same ball with both front- and back-illumination, normal intensity. Surface structure, shape and solder wetting are visible.
BGA lens is Refocused. Bridges, contamination, fibers, excess flux are visible now.
Front light intensity is increased! Surface structure of second row bumps become visible!
Normal intensity front-light (incident) only. Normal intensity front and back-light.
Normal intensity front- and back-light.Refocused on thirds rows of bumps.
Extra intensity front- and normal back-light.Refocused on second rows of bumps.
